When Microsoft released Halo 3 ODST the team came to me for their cake to celebrate the release. Their unofficial mascot is apparently the unicorn. Originally I was going to use a projector to make this cake, but it broke and fell into the first cake as I was adjusting the focus, so I did this freehand.

The team that made the soundtrack for Halo 3 was so impressed by my work that they came in a couple days later and asked for a cake as well based on the cover art of the game. This was also freehand.
